Is there a license / royalty free DRM available for protecting and distributing content? [closed]

"DRM is encryption. The way encryption works is that you have a key that can open the lock, and that key is given only to people you want to be able to access the content, and kept away from people who you don't want to access it.

The reason that DRM is flawed is that the person you want to access the content and the person you want to keep access from is the same person. It just doesn't make any sense. The only way it sorta-kinda works is that keys are given to a tool that is restricted in its use. But that tool has to keep the key away from the user. In order to use that tool, you have to use a lock that matches one of its keys.

At this point you ask, ""why can't I just add my own key?"" And you might be able to. But the only way to get that key into the tool is to give it to he person you're trying to keep it away from. It's like asking a burglar to give your housekeys to your roommate for you."
